crust, exposed thereby, will readily ignite on the application of the flame of the match. Upon rfi-lighting the heat of the flames at the openings a in the crust of the soap mixture formed on the surface of the mass, will melt and, by reason of the surface tension, form globules thereby exposing a fresh surface underneath upon which a new film 8 of soap mixture will he formed to be melted in its turn u on beine broken and re-lisjhtefi.v

and so on until all the alcohol is consumeci.

When the' film or crust 7 or 8 is being formed by reason of the burning of the hiel it (the crust orv film) is of a more or less porous nature so that the fuel. beneath it may be consumed by the iiame anti the crust Upon cooling the crustl will harden.

On relighting, the crust 8 Will be punct'urecl as before. The heat of the flames at the openings?) will melt the crust 8 and. the globules 8 formed from the previous crust or crusts and the'meltecl soap mixtures will unite ancl form larger globules.

The usual method of extinguishing the flame is to invert the cover 6, and slide it over the flame opening 3f. As the can or conn tainer, however, becomes very much heated when the fuel is burning, the container cannot be safely handled until some time after the flame has been extinguished and the cover cannot be tightly inserted in the flame opem ing;v until the container becomes cool enough to handle. The result of this is that the operator may forget or neglect to properly seal the container and were' it not for the presence ot the film or crust, the' alcohol would evaporate and the mass in the conu tainer become useless for heating purposes While I have described my fuel com-- posed principally of ethyl eicel-iol, prefer iny order to prevent the deposit-ion of free carbon on the bottom of the vessel holding the lingredients to be heated, to use a amount of material having; a smaller carbon contenti than ethyl alcohol, for example methyl alcohol, and by proportioning these materials, say one part of methyl alcohol by volume to three parts of ethyl alcohol by volume. In practice I prefer, for reasons of economy, to ,use what is known as the Unite States formula #l denatured alcohol.

It the alcohols contain too much water for my pu `pose I may remove the excess by listillingv with calcined lime and finti l satisfactory material when there about from three and a half to four of water in the finisheflv piotiuctc ilenerally speaking, my product improves as the water content decreases up to a certain point.

One formula for producing my material consists in heating l0() cubic centimeters of partly dehydrated alcohol to from 7G to C.. then dissolving in this tour anti onehai" grams of triple pressed stearie a-cicl, then neutralizing the major portion of this fatty acid with sotlium hydroxirl. lf the alcohol has been dehydrated to "mt 98%, I nd it feasible to use an aquec, solution, lV density of "0 Baume o sodium hyd;

0') for neutralizing the fatty acid. If the hol not been dehydrm4 then l dissolve the soclii. hydroxid in a part of the alcohol and t triple ressed stearic aeid in the balance of 'the alcohol and incorporate themv when they are both heated to the above temperature. J

Instead of mixing the stearie acid and sodium hytlroxid and forming a soap in the alcohol, l may dissolve say 4% of sodium stearate. in the alcohol and then add a small amount. of tree stearic acid or not, as I may or may not desire a free fatty acid in the fuel as explained above.

The mixture while hot is 'ourecl into the container anni the cover p aced tightly in position in the flame openinfr. The fuel is usually dispensed in the container in vwhich it. is burned.

The fuel mafie in this Way will not liquefy from the heatof the flame on the burning surface but will remain in its jellied state. The soap which forms and is melted on the top of the burning mass is of a thick, viscous, tacky nature, and will not escape even if the can be over-turned and will not be reab sorheti bythe mass of the fuel either when rit (the soap) is hot or cold.

is long as the soap is combined with the alcohol in the mass in solid form, the mass will not be melted by the heat of the flame on surface of the alcohoh The amount of soap in the mixture is relatively small and will not become ignited in the flame of the cobol ami there will he no anger of lire if the *hiel were burned with the can inver'eol anu the melted soap permitted to clrop vrom the flame opening. .1.oreover, by referring to the drawing: it will be seen that the top 3 and wall 5 will prevent any loose particles of the soap from dropping from the can except in the event of the can being entirely inverted,

in 'accor-(lance with the provisions of the patent statutes l have described the principle of my invention, together with the appairatus which l consider to represent the best einborliinent thereof, but I desire to have it ruilcrstootl that the apparatus shown is illustrative, and that the invention y be carri-ed out in other ways. l
